Definitions

  • the present invention relates to a window with an emergency exit function for a helicopter.
  • the present invention also relates to a method for removing a transparent element from a window with an emergency exit function.
  • the normal service exits of the helicopter can also be used as emergency exits.
  • the windows are defined by a door made in the helicopter's fuselage and essentially comprise:
  • the helicopter's occupants or rescue workers exert a force on the transparent element so as to break the glue joint by means of a cord and pull the transparent element away from the door.
  • the window proves to be particularly heavy and the fitting/replacement operations, of the transparent element require a significant amount of time.
  • US 2367035 discloses a window with an emergency exit function according to the preamble of claim 1, and a method for removing a transparent element from a window with an emergency exit function for a helicopter according to the preamble of claim 10.
  • the object of the present invention is to produce a window with an emergency exit function that solves at least one of the above-identified drawbacks associated with known types of windows, in a simple and inexpensive manner.
  • the present invention also related to a method for removing a transparent element from a window with an emergency exit function for a helicopter, as claimed in claim 10.
  • reference numeral 1 indicates a helicopter.
  • the helicopter 1 essentially comprises a fuselage 2, a main rotor 3 rotating about an axis and a tail rotor 4 located at one end of the fuselage 2 and rotating about its own axis, transversal to the axis of the main rotor.
  • the fuselage 2 in turn comprises:
  • These windows 7 is sufficiently large to allow the occupants of the helicopter 1 to climb through and thus escape.
  • the windows 7 also perform the function of emergency exits.
  • the window 7 comprises ( Figures 2 and 3 ):
  • the transparent element 10 In order to perform this emergency exit function, the transparent element 10 must be removable from the frame 8 with a force below a threshold value, for example 20 kg.
  • This force can be applied from inside the fuselage 2 by the occupants or from outside the fuselage 2 by rescuers.
  • the transparent element 10 comprises ( Figures 4 and 5 ) a main portion 11 lying on a plane P.
  • the transparent element 10 also comprises a face 10a arranged on the inner side of the fuselage 2 and a face 10b, opposite to face 10a, arranged on the outer side of the fuselage 2.
  • the transparent element 10 is made of a plastic material or glass.
  • the transparent element 10 is delimited by:
  • edges 13a and 13b of each pair extend with one along direction A and the other along direction B.
  • the transparent element 10 comprises, at each edge 13a and 13b ( Figures 4 to 6 ):
  • the walls 12 converge towards the main portion 11.
  • the door 6 comprises, for each window 7, ( Figure 3 ):
  • the wall 51 extends from the side of face 10a and wall 52 extends from the side of face 10b of the transparent element 10.
  • the window 7 also comprises a seal 49 defining a closed profile lying on plane P, formed by four sides and having a shape corresponding to the profile of the transparent element 10.
  • the seal 49 is interposed, along a direction orthogonal to plane P, between face 10b of the transparent element 10 and wall 52 of the door 6.
  • the frame 8 is formed like a window frame with a shape substantially corresponding to that of the transparent element 10.
  • the frame 8 has a quadrangular shape, rectangular in the case shown.
  • the frame 8 is connected to walls 50 of the door 6 by means of connection elements 23 and 24, which are shown in Figures 3 to 5 .
  • the frame 8 comprises:
  • sides 25 and 30 are shaped like tongues.
  • the frame 8 is made of a plastic material and sides 25 are thin-walled.
  • Sides 30 are adjacent to each other, interposed between sides 25, and converge in a corner 16, opposite to corner 15, of the frame 8.
  • the corners 15 and 16 are curved and connect the respective sides 25 and 30 to each other.
  • Sides 25 and 30 extend along direction A and the other along direction B, and have a height along a direction C orthogonal to plane P.
  • the transparent element 10 is also fitted with the handle 18, which is positioned in corner 15.
  • the handle 18 protrudes from face 10a of the transparent element 10 towards the inside of the fuselage 2.
  • connection elements 23 and 24 are also connected to sides 25 and 30, respectively, of the frame 8.
  • connection elements 23 and 24 are shaped ( Figures 3 to 6 ) like wedges, each delimited by:
  • Sides 25 comprise respective sections 21 ( Figure 6 ) converging in the corner 15 and respective sections 22 ( Figure 5 ) opposite to the corner 15, i.e. arranged at the side of the handle 18 ( Figure 3 ).
  • Each side 25 essentially comprises ( Figures 3 to 6 , 10 and 11) :
  • portion 41 When force F is below the threshold value, portion 41 is arranged abutting against the transparent element 10 at each section 22 and is spaced apart from the transparent element 10 at each section 21.
  • portion 41 defines a shoulder 45 engaged by edge 13a of the transparent element 10.
  • the shoulder 45 is defined by a pair of walls 46 and 47 converging to each other in a corner.
  • wall 46 When force F is below the threshold value, wall 46 is arranged abutting against the respective wall 12 of the transparent element 10, while wall 47 is normally arranged abutting against the respective wall 14 of the transparent element 10.
  • the walls 46 and 12 overlapping each other are flat.
  • walls 46 and 12 progressively move away from face 10b of the transparent element 10, starting from edge 13a and proceeding towards the main portion 11 of the transparent element 10.
  • section 21 of each side 25 comprises a recess 20 ( Figures 6 and 11 ) delimiting the release 17 and shaped so as to maintain the distance between section 21 and the transparent element 10.
  • portion 41 of each side 25 is interrupted at the respective section 21.
  • the recess 20 thus defines a trigger zone for bending side 25 in the area of the handle 18 following the application of a force F on the transparent element 10.
  • the transparent element 10 fails to move sides 25 along the direction C.
  • the transparent element 10 thus remains fixed to the door 6 by sides 25 and 30.
  • the transparent element 10 is able to move the sections 21 of sides 25 transversely to the direction C due to the presence of the recess 20 and cause the consequent elastic bending of sides 25 in plane Q.
  • wall 12 of the transparent element 10 becomes disengaged from side 25 and therefore from the frame 8, also on sections 22 of sides 25.
  • Each side 30 essentially comprises ( Figure 4 ):
  • portion 60 is delimited along the respective direction A or B by a surface 63 arranged abutting against surface 33 of the respective connection element 24.
  • Portion 61 defines a shoulder 64, which is engaged by walls 12 and 14 of edge 13b of the transparent element 10.
  • shoulder 64 e defined by a pair of walls 65 and 66 converging to each other in a corner.
  • Wall 65 is arranged abutting against wall 12 of the respective edge 13b, while wall 66 is arranged abutting against wall 14 of the respective edge 13b, for all values of force F.
  • wall 65 is shaped quite similarly to wall 14, i.e. it is inclined with respect to plane P and converges from wall 66 towards the main portion 11.
  • Portion 62 is L-shaped and in turn comprises, proceeding from portion 60 towards portion 61:
  • portions 61 and 62 particularly thick on plane P with respect to sides 25, gives side 30 a much greater flexural rigidity in plane Q than the flexural rigidity of the sides 25 in response to a force F orthogonal to plane P.
  • portions 60, 61, and 62 do not elastically alter their position significantly and continue to press walls 12 and 14 of edge 13b against seal 49 and wall 52 of the door 6.
  • the transparent element 10 can be easily detached from side 30 of the frame 8 by a force G ( Figures 4 and 9 ) having a direction lying in plane P and oriented so as to pull the transparent element 10 away from sides 30 and from walls 50.
  • wall 65 does not constrain walls 12 and 14, converging to edge 13b of the transparent element 10, in any way when force G is applied to the latter with its main component in plane P and oriented in the opposite direction to wall 50 of the door 6.
  • walls 65 and 14 are configured so as to move away from face 10b of the transparent element 10, starting from edge 13b and proceeding towards the main portion 11 of the transparent element 10.
  • the window 7 also comprises a plurality of connection elements 70 ( Figure 7 ), which are configured to support the aerodynamic loads acting on the transparent element 10 and to allow the removal of the transparent element 10 from the door 6 when force F exceeds the threshold value.
  • connection element 70 is arranged in corner 15 of the transparent element 10.
  • connection element 70 is an insert, housed inside a seat 71 of the handle 18.
  • connection element 70 essentially comprises:
  • end 74 is interposed between face 10a of the transparent element 10 and portion 41 of side 25.
  • connection elements 70 are sized so as to resist, under the action of aerodynamic loads, force values below the threshold value.
  • each connection element 70 is sized so as to be able to support aerodynamic loads acting on face 10b and to hold the transparent element 10 in position, due to the abutment between end 74 and portion 41.
  • connection elements 70 are fixed to the transparent element 10 on edge 13b.
  • the window 7 is used as an emergency exit. More specifically, the occupants simply remove the transparent element 10 from the door 6 and climb through the opening 9 freed of the transparent element 10. In an entirely similar manner, the transparent element 10 can be removed from outside the helicopter 1 by rescue workers.
  • the removal of the transparent element 10 from the door 6 takes place by exerting a force F greater than the threshold value on the handle 18 - or on face 10b of the transparent element 10 itself - in a direction orthogonal to plane P and directed towards the inside of the fuselage 2, and then exerting a force G with the main component parallel to plane P on the transparent element 10 itself in a direction away from sides 30 of the frame 8.
  • the transparent element 10 when force F is greater than the threshold value, and also thanks to the presence of the recess 20, the transparent element 10 is able to move sections 21 of sides 25 arranged in the zone of the handle 18 transversely to direction C.
  • the transparent element 10 is only constrained to the frame 8 by sides 30, as shown in Figure 10 .
  • sides 30 do not prevent subsequent detachment of the transparent element 10 following the application of a force G having a main component parallel to plane P.
  • wall 65 is shaped so as not to restrain wall 12 of the transparent element 10 along the above-stated direction parallel to plane P when a force G is applied in a direction away from side 30.
  • the application of force G enables easily detaching the transparent element 10 from sides 30.
  • the transparent element 10 is completely removed from the door 6 and no longer occupies the opening 9, which can be used to evacuate the fuselage 2.
  • connection element 70 prevents the aerodynamic loads acting on face 10b of the transparent element 10 from causing undesired fortuitous removal of the transparent element 10 from the door 6.
  • the frame 8 of the window 7 comprises:
  • the window 7 does not require any glue joint to be broken to enable pulling the transparent element 10 away from the door 6.
  • the transparent element 7 is removed from the frame 8 by simply applying force F transversal to plane P so as to elastically bend and move sides 25, away from sides 30, and then also detach the transparent element 10 from sides 30 by applying a force G parallel to plane P.
  • a window 7 is thus obtained that has a transparent element 10 substantially free of vibrations during flight of the helicopter 1 and, at the same time, easily allows removal of the transparent element 10 in case of necessity.
  • the window 7 can be completely installed from inside the fuselage 2, by simply:
  • the window 7 has a particularly pleasing aesthetic effect and does not negatively affect the aerodynamic profile of the fuselage 2.
  • the window 7 has a much lower weight - approximately 50% - than the solutions discussed in the introductory part of this description, with evident advantages in weight reduction and/or increase in payload of the helicopter 1.
